As a layman I would think that although the load factor at Va may exceed nlimit, the load would not exceed limit load.
The limit load (assuming the aircraft is designed by manoeuvre loads not by gust loads) would be 2.5g at MTOW and fwd CG limit. Strictly speaking that should be at MTOW less whatever fuel you burn to get there, but WTH! At Va you can just pull 2.5g at whatever weight has been used to define Va.
So if you are at a weight close to MTOW and at a speed above Va
for that weight then you could in principle exceed both the 2.5g limit and the limit load. But at those conditions it is unlikely that one could pull enough 'g' to get anywhere near ultimate load (3.75g @ MTOW) if only because to get to a weight/airspeed condition where one could pull 3.75g one would have to burn off enough fuel to reduce the weight well below MTOW.
