Honestly not really. Hindu was the widely used demonym to refer to any Indian before Hindu nationalists decided to turn it into a religious designation. To be a follower of the Hindu religion meant that you followed some set of practices that originated in India. There was no requirement that they be the same standard set.

Modern day Hinduism is a post-hoc reconstruction. That's not to say Indian religious beliefs and doctrines don't exist -- they do. There are just a wide variety of them and they deserve their own mentions.
