Yes. "yum grouplist" will tell you the groups that are currently in the
installed state. Worth reading the manpage to see exactly what yum
thinks that "installed" means:

     Groups are marked as "installed" if all mandatory packages are
     installed, or if a group doesn’t have any mandatory packages then
     it is installed if any of the optional or default package are
     installed. [...]
