No, not in any normal sense of those words that I know.

And if not?  :-)

N3 expressions can be described in RDF, and described formulas
(truth-valued expressions) can be claimed to be true or false in RDF,
so N3 can be carried inside RDF, but that's not surprising at all,
since English can be carried as well (eg in rdfs:comment triples).

I understand that although my above claim is pretty obviously true in
a naive sense, there may be serious problems in the details, and that
you are not yet convinced those probably can ever be solved.   This is
the problem I talked about in the rest of the RDF section of the SWRL
