You won't be able to delete them. If you want to avoid anyone telnetting into the router, the commands you already have along with no login should do it.

Actually no login will not do it. What no login will do is to allow access without checking any password. Configuring no exec is a much better way to make sure that no one uses them. And transport input none is pretty effective.
