It's surely worth trying to move it although I'm sure some people would say, leave it and treat yourself to a new one. However, I've read of several people who have moved their Acer before it starts to come properly into leaf. I'd dig it up now for it to stand the best chance. Taking as much soil around the roots as you possibly can and keep it well watered after you've put it into it's new container. Good luck, do let us know how you get on.
