No not really, BP currently is a 'one team' set up, and you have to invent any 'multi-team' working practices yourself. Naming conventions are a basic measure, but operational/security preventions, aside from creativity with credentials etc, are not there yet. Soon, but not yet.
If you go down the separate environment route, you'll need to think about licensing as legally you can't reuse the same license in two production environments. We can easily reissue new licenses to keep you within compliance though.
