Is the grounded conductor in a 2-wire 230/240 volt system fed to each
home
referred to as "neutral" even in UK?

Yes, although we have 3 types of supply arrangement for earthing
used on public supplies. (Note that on 240V, there's often far
more distance between the consumer and the transformer than
you'll find in the US on 120V supplies.)

TN-S:
Neutral is grounded only at the transformer, but a separate
earth conductor is carried in the supply network and brought
into the home from that same grounding point.

In the USA they ground the Neutral at the transformer and do not run
a seperate ground conductor to the house. There is however a ground
rod driven which is tied to the neutral at the entrance to the house.
