In short, yes, very possible. There are certain shapes that were very unique. For example kambun shinto is one of the more easily recognized shapes in kantei, which presents a specific window. There is also as DB indicated, 'replies' that are used to infer early, mid, or late.
One Japanese polisher I met had an interesting little book that he referenced to narrow down his initial time period kantei (eg. muromachi, nambokucho, etc), to a specific era based on the specific shape and dimensions of kissaki.
