No, not yet. But...

... if you used redland store which did inference, that may let you do
that kind of question. The 3store backend is in progress and (in CVS,
working) will be in the next release and does handle most RDFS
entailments, which would then answer your question 'yes'. This
partially depends on changes in 3store inside their CVS version,
i.e. they have to make a release first too
