Yes, you can add a playlist to a playlist. I do it frequently.

If you are playing an album and choose to save to a playlist, it gives that playlist the same name (and art) as the album. What else would it do? Deleting the playlist does not delete the album, why would it?

I can definitely see your confusion, and I'm sure it could be better-designed. That said, I never have any issues, and playlists are my primary use case for Apple Music.

Remove the Downloads removes the corresponding album, so I'm not inclined to find out if Delete from Library does the same thing.

Why wouldn't they call it "Delete Playlist"? And why does Remove the Downloads remove the underlying album, instead of the correct behavior, which is to remove the playlist from my phone but keep it in the cloud and my other devices?

This is bad no matter how you gloss it.

If I click Remove the Downloads on a playlist that isn't based on an album, is it going to remove those individual tracks from my phone?

When would that ever be the behavior that someone wants? Actions on a playlist should be limited to that playlist, this is UX 101 stuff.

That depends on what you've chosen for the setting related to that. If you 'Add songs to library when adding playlist,' then no, the songs/albums remain. Otherwise, the playlist is your only view to that music, and so removing it removes your only view.

I believe the default is not to add songs to your library when adding a playlist, so deleting the playlist removes your view.
