Not quite. As mentioned in the specs table from the official release thread:

The base model M3/M4 uses the O0 while the Competition model uses the T0. As far as I know, the same is true for the X3/X4 M. I mean it's on Wikipedia, so it must be true.

But, no, in all seriousness I think they genuinely do use the same engines, it's just that as xlover points out, the ECU tune is different for the M3/M4 (higher peak torque).
