Solaris contains OpenSolaris, so in general the answer is yes.
However, that only holds for the same version or build number.  You
cannot, for example, build (or run) a current OpenSolaris kernel on
Solaris 8, 9, or 10.  Check out the release notes for ON (which
contains the kernel) at
http://dlc.sun.com/osol/on/downloads/current/README.opensolaris and
the known issues page
(http://opensolaris.org/os/community/onnv/known_issues/) for
information on the requirements to build the latest sources.  There's
some chance that it's possible, with some work, to build recent ON on
the latest S10 update, but I'd lay heavy odds against it.

To learn more about the relationship between OpenSolaris and Solaris,
