Were any of the above categories included in a previous CAA/JAA definition rather than an EASA one?
Yes, EASA has used a completely different definition for a completely different purpose.
Interestingly, JAA never defined a "complex" aeroplane in JAR-FCL 1. In LASORS the CAA defines it as "an aeroplane certificated for the carriage of at least four persons, have a variable pitch propeller and retractable landing gear", though the definition is only used in requiring a certain amount of complex time in CPL training. Differences training is required for a number of features in the list you quote (VP, retractable, turbo, pressurised, tail-wheel) but the "complex aeroplane" definition is not used, nor is the number of seats ever referred to.
The FAA defines it as "an airplane that has a retractable landing gear, flaps, and a controllable pitch propeller". This is
one of the things that requires differences training in FAA-land. Others include high performance (> 200 hp), pressurized and tail-wheel.
