As long as your flight is on time, the MCT (35 mins?) is more than adequate.
Yesterday (arrival from A departure from C) it took me less than 20 minutes to get out of the plane, go down the steps, enter the bus, be driven to bus gate, go upstairs from bus gate to terminal, visit transfer desk (and wait for previous passenger to be served), walk across to other terminal, clear security (no separate passport control done) and go to the lounge 2 floors up. Lounge was 4 minutes from gate (if you didn't go to the lounge, the gate was 2 minutes from security).
Granted, I was walking briskly and, after having done an unhealthy number of PRG connections, I know my way around quite well, but, in all likelihood, your journey between gates will be much simpler!
