I suppose it is possible that you can reach max elevator
without reaching critical AOA. But I think that is unlikely, because
that would mean you will never be able to perform power-off stalls in
level unaccelerated flight.

The horizontal stabilizer and elevator are sized so that you can reach
max lift coefficient under the most extreme conditions, which will be
forward CG and in ground effect.

Since GE increases the stability of the aircraft, it is possible that
you could stall at altitude, but not close to the ground.
