Yes, but MPLS was built with an idea to speed up forwarding, since at that time the routers/switches were not that fast. So increasing the label size would not have seemed like a nice idea at that time. Also think of the following: A---B---C---D Since the labels are of local significance, C can assign a label without caring what label A,B or D has assigned to other flows. I can think of only these reasons.
