I have installed the latest version of BBPress on a WP Multisite install, on in its own subdomain, which I guess I could map with a cname if it would help solve this problem.

I did this so that I could theme the forums differently to the primary domain.

The url looks like this now… http://forums.domain.tld/forums/

Is it possible to run BBPress as the forums subdomain, and not the subdirectory?

Yes It Is Possible… 🙂
Just Go Through Your Hosting Cpanel And Once Check Your Installation File 🙂
