Simplistically, not necessarily.
The protections are pretty much fool proof against a pilot induced high aoa/low energy state being achieved - it just won't let you command the plane into trouble (again, simplistic) - but subject the aircraft to a massive external disturbance, and there's not a lot the FBW can do if the disturbance is too big. If full nose down elevator isn't enough to prevent an externally induced pitch up, the FBW is along for the ride, just like a crew of a conventionally controlled plane.
This is where we get the difference between "An airbus cannot be stalled" - which is kind of true, as it implies that this is a "commanded stall", and thus the FBW can simply prevent the pilot from causing the stall - and "An airbus cannot stall" which implies magic aerodynamics that work at 90 degrees AOA, and which neither Toulouse nor anyone else has the ability to create.
