If a major power surrenders but it still has aligned minors it will continue to fight using those minors (and collect MP). The problem is they can not research as the research screen is not available to them.

The production screen is available and they can build units for all the aligned minors.

I was able to do duplicate this by creating a bunch of French Colonies and when France surrenders some of their colonies will continue to fight under the French Flag.

This is correct as it is the major power that performs research (and diplomacy) and the minors get the benefit of that research. Purchases can continue to occur for the minor, as they did prior to the major surrender, so this seems consistent.
