Nope. Armored cruisers were pre-WWI ships, and were outdated by the time that the first Battlecruisers appeared. The last armored cruiser (arguably the best) was SMS Blücher, sunk in 1915...by battlecruisers

the terms and differences between "heavy cruiser" and "light Cruiser" were created in 1922, in the Washington Naval Treaty. As you say, were ships up to 10.000 tons, with 8' or 6' respectively. BUT BOTH KIND OF SHIPS COULD BE ARMORED. And in fact some light cruisers had more armor than some heavys.
the term "Armored Cruiser" was not used again after WWI, and the CA term has nothing to do with it AFAIK.

I believe that Armoured and Light cruiser
CA and CL where distinctions that made scence when they were orginated. By WW2 they merely denote 6 inch or 8 inch gun. The same hull converted from 6 to 8 inch guns would be classed from a CL to CA.
Not to nitpick.
CA meant Cruiser Armoured.
