If you have a peanut allergy, can you still drink almond milk?

Maybe: It all depends if you have an almond allergy. Almonds fit into the category of "tree nuts." individuals with a true peanut allergy have ~35% chance of a concomitant tree nut allergy. If you are able to eat almonds without any adverse reaction on a regular basis, then you should be able to drink almond milk. However if you avoid tree nuts in general, i would consult a board-certified allergist.
