No wing will stall if the G loading is zero so pushing or pulling depends on if the Gs are positive or negative. Move the elevator to unload the G loading.
If you happen to be going straight up when you do this using rudder and making a flat yaw with the ailerons will put you in a vertical dive known as a hammerhead stall even though the wing is not stalled even when the airspeed approaches zero. I have taught hundreds of these in aerobatic planes but wouldn't suggest it in an airliner even though it might work fine if you could keep the wings flat in the rotation to vertical.
