As i know the answer is NO, it can't be considered as a smothered mate. The smothered mate should involve only a Knight threating and mating the King.
Notice also that a mate with a double check with a Knight delivering the one check, is not a smothered mate. For example the following is not:
r1b1k2r/p3qppp/1p3B2/2pP4/8/2P2n2/PP1N1PPP/
