The pressure difference is trivial. The reason it has to be thicker is because the top is flatter than the sides (convex) and bottom (concave). If the top was domed up it could be thinner. Have you ever seen an overheated or frozen can? The top is usually bulging while the rest is still intact.

Actually most frozen cans have the bottom inverted, but I've only noticed this happen since about 2010. It used to be that a fully frozen can always used to blow.
