Not exactly.  They forked at some point long ago.

I don't know what it would take.  We are probably not going to support
the use of Boost.Jam as a pure build engine, without the Boost.Build
v2 build system, but if you want to try it on your own, it will probably
work if you just rename "bjam" to something else (e.g. "jam") and
don't have BOOST_ROOT set in your environment.  See the Jambase file
in the Boost.Jam source for the reasons why that might work for you.
