Sorry, don't really know for sure, I'm not 'that' old :-D
But I wouldn't think so, although 'my bees' often use 'older' drone comb as honeycomb, but I've never had comb older than five years old in my hives.
Not sure about extracting either, but again I wouldn't think so (kinda dirty), We harvest our honey in chunk form from the 'newest' comb, leaving the older comb for the bees.
