In theory yes. However this isn't the official rule in ANY disney park so don't rely on it and for the sake of others, try to get there in the allotted time slot
There is courtesy, then there is abusing a privilege. I would not use a fastpass beyond 1/2 an hour, hour max. While they don't always, some do inforce it.
I was told that DLP doesn't let you use it after your allotted time. When I went I was really careful about it. I heard a CM tell a guest that they can use it all day. I was there during a slow time, so that might be why they were lenient.
