Yes, that is one of the very few technical exceptions.

However, if you require access to the DFS which is
typically a domain resources, then it is a poor practice
to have DFS server(s) without a DC to authenticate
locally.

And of course, given that there is a DFS server it
costs nothing and is little trouble to put the DC on
the same server (at worst.) Same for DNS.
