Yes it does.
They say it has zero GRAMS of lactose (At least on the cheddar sitting in my room). Aged cheese doesn't have much lactose in it, but pretty much all cheese has some. In fact, even Lactaid Ice Cream which claims to have no lactose at all has some in it. So while any aged cheese will have little enough lactose that even many lactose intolerant individuals will be fine as long as they don't overindulge, but I imagine the amount in the cheese is low enough so that they can claim it doesn't have any.
Unless you are lactose intolerant, yes.
