Indeed, every Yade simulations require usually much more than 2 engines.
As such, it is possible.
As for your problem, the error message points you to line 121 o

I try to impose the velocity on the piston without using O.engines
To impose the velocity i write: O.bodies[piston].state.vel[1]=1
and this a part of the script:
from yade import ympor
