They do. For example, goju ryu has two main branches: The Okinawan and the Japanese version began by (Cat Man) Gogen Yamaguchi. There are now likely further subdivisions within these. There are several branches of shorinryu as well: Chibana Chosin's kobayashi. Eizo Shimabuku's shobayashi and Zenryo Shimabukuro's seito and Shoshin Nagamine's Matsubayashi shorinryu. These last three all studied with Chotoku Kyan (I don't know what he called his style, if anything, being from the time prior to formal styles. Maybe he just called it Shorin?Just a small comment on the original question....
I studied Shotokan Karate for about 15 years... Well, actually it was Kenkojuku Shotokan Karate.

So, I do know that at least for Shotokan, there are different styles within that main style. I would not be surprised if the other styles of Karate also had their own styles within as well.
These branches are basically the same with just minor variations and sometimes a different kata or two in the curriculum. As for the kenkojuku Shotokan you studied, it seems from my quick research has a bit of early Funakoshi O-sensei's Okinawan flavor that was lost just prior to WWll and the JKA's modernization of it. Other karate styles I'm not that familiar with surely have some substyles as well.
