Maybe, not sure! this lower CAS speed limit is introduced for maintenance.
That would be an unfortunate tail wagging the dog approach to a minor engineering problem.
With a computerized aircraft you no doubt have maintenance modes you can enter (that are locked out during flight operations). Besides, how do you test the stall warning system on the ground then?
The 60 knot limit below which AOA is disabled more than likely results from another corner of the envelope. Something such as flow impingement from thrust reversers at low speed (on the ground of course).
