Orwell himself made the claim that Huxley must've known of We, so yes, Orwell certainly knew the work. From TFA:
Orwell began Nineteen Eighty-Four (1949) some eight months after he read We in a French translation and wrote a review of it.[28] Orwell is reported as "saying that he was taking it as the model for his next novel".
