I have at times placed a super under the brood chamber for winter, when a super has stores in it not suitable for extracting.
I haven't done it as a 'matter of course' but I know beekeepers that do.
Some put supers (even if dry with no stores) under the brood box to provide some protection against strong winds in exposed apiaries.
