Activating BuddyPress inside an existing page


I'm using MarketPress on a multi-site for an Etsy-style site. I am using the GridMarket child theme.

I want to make use of BuddyPress, but I want it to live in one place on the site called "VENDOR HUB" - which is currently a page that's part of main navigation under "Vendors."

I want people to be able to go to the VENDOR HUB and get a log in to access the social network. Can I do this using BuddyPress?
