Sure it's legal. As it stands only 4MJ (which amounts to about 33 seconds per lap) can be transferred from the ES (Energy Store/Battery) to the MGU-K per lap and only 2MJ can be transferred from the MGU-K to the ES per lap. However you can transfer an unlimited amount of energy from the MGU-H to the ES/MGU-K and thus boost power for longer periods.
I am unsure if the 50 seconds is inclusive of the 4MJ though.
