Looking at the PV above it seems possible indeed.
I tried it with my Super Forte C (6502, 5 MHz) in Infinite mode:
After ~ 30 minutes and complete analysis of depth 8 he plays 10... Be6 (score
+0.14) with the following 11.Bd2/Qc7 12.Ng3/Nbd7 13.b4/Nb6 14.Rc1.
10 ...Bxh2 didn't appear as best move within these 30 minutes.
