This is because of the System Integrity Protection (SIP). 
You can disable it (not recommended) and remove the kext manually.

(from <a href="https://www.imore.com/el-capitan-system-integrity-protection-helps-keep-malware-away" rel="nofollow noreferrer">https://www.imore.com/el-capitan-system-integrity-protection-helps-keep-malware-away</a>)

If you decide later you want to re-engage SIP (and I earnestly hope that you do), repeat these steps, use <code>csrutil enable</code> instead.

I had a similar issue in trying to uninstall the TelestreamAudio.kext for ScreenFlow. What might be happening is that the kext in StagedExtensions is currently in use or protected while you're in regular mode. Once you get into Recovery mode, you can delete it without disabling System Integrity Protection. The following steps worked for me, though please use caution.

<ul>
<li>Click the  menu. Select Restart</li>
<li>Hold down command-R to boot into the Recovery System</li>
<li>Choose Disk Utility from the Recovery Menu</li>
<li>Within Disk Utility click on your main hard drive (e.g. Macintosh HD) and then click on Mount</li>
<li>Exit out of Disk Utility</li>
<li>Click Utilities in the menu bar and select Terminal</li>
<li>Use the following commands:</li>
</ul>

.

<pre><code>cd /Volumes/Macintosh\ HD/Library/StagedExtensions/Library/Extensions/
rm -rf NAME_OF_EXTENSION.kext
</code></pre>

<ul>
<li>Close the Terminal app</li>
<li>Click the  menu and select Restart</li>
</ul>

From there on, I was able to reinstall ScreenFlow's audio kext and it worked. It may also help you completely remove the Parallels kext.

In my case, deleted kext disappears from StagedExtensions when you invalidate kext cache.

<pre><code>sudo rm -rf /Library/Extensions/Parallel\ Desktop.app # check if the name is correct so you don't delete some other kext
sudo kextcache -invalidate /
# now you should not see your deleted kext here
ls /Library/StagedExtensions/
</code></pre>

UPDATE 2019:

See man page for full details: <code>man kextcache</code>.
Excerpt related to <code>-invalidate</code>, <code>-i</code> for short:

<pre><code> -i os_volume, -invalidate os_volume
 Rebuild out-of-date caches and update any helper partitions
 associated with os_volume.

 This option mimics sudo touch /System/Library/Extensions on
 os_volume. If kextcache cannot find or make sense of
 os_volume/usr/standalone/bootcaches.plist, the volume is treated
 as if no caches need updating: success is returned.
</code></pre>

There are also new options:

<pre><code> -clear-staging
 Clears the kernel extension staging area by removing all staged content.

 -prune-staging
 Prunes the kernel extension staging area by removing all kernel extensions
 no longer present in their original location.
</code></pre>

Looks like <code>-prune-staging</code> removes only the deleted extensions, shaving little bit of time from the next kext cache rebuild.

See <a href="https://www.unix.com/man-page/mojave/8/KEXTCACHE/" rel="noreferrer">https://www.unix.com/man-page/mojave/8/KEXTCACHE/</a> for Mojave man page, which contains these new options.

Was in folder <code>HD/Library/</code>

Cheers

Edit: Formatting

Edit2: I believe that Parallels writes some files directly into the bootloader/kernel. After running the command from the CMD+R hold restart Disk Utility Terminal the extension was removed from /Library .

I hope this makes sense.

If you've already deleted the extensions from <code>/Library/Extensions</code>, open the Terminal app from Launchpad, copy/paste the command below and press Enter to run it:
<code>sudo kextcache -prune-staging</code>
As mentioned in another comment, this will only remove the kernel extensions that are no longer present in their original location, i.e., <code>/Library/Extensions</code>.
The extensions you deleted from <code>/Library/Extensions</code> will then disappear from <code>/Library/StagedExtensions/</code>. It won't affect your other kernel staged extensions.
<code>/Library/StagedExtensions/</code> is an intermediate area where your extensions live after you start your session (like a cache). The staging area won't be immediately affected if changes are made to <code>/Library/Extensions</code>, which I believe is meant to improve stability and security.

I'm trying to uninstall Parallels completely from macOS High Sierra.
I removed everything from the disk except some Parallels extensions that are stored under /Library/StagedExtensions/Parallel Desktop.app

I think the location has to do with user approved extensions, but I'd like to find a way to remove/uninstall those too. If I try to delete the extensions it says operation not permitted despite the root rights.

Any idea?
