Sure but try to rewrite it in your own words. Dublicate Content is deadly for SEO (Search Engine Optimization) and senseless for the internet as a public database of information.
To complement your knowledge:
4 or 5 years ago there was a working plugin for the standalone-version. But bbPress now is on the one hand a Plugin for WordPress and on the other hand it has gone through some serious changes (Updates/Improvements).
I’m not sure if there’s still a standalone version managed and maintained by the developers. But in the past there were working methods to customize the URL structure individually (Mostly “core-hacking”).
