I think the iron should work.
Several months ago a reader wrote in to the "This Old House" magazine and had a question about laminate. Apparently they had set a pot that was too warm on the laminate, it heated up the adhesive making it release and then caused a bubble on the countertop. I think Tom Silva's suggestion was to reheat it with an iron (through a towel, so as to not scorch it) and then weight it down.
I would think you could do the reverse; heat it and then try to scrap it loose.

Good luck.
