That is CORRECT.
There has never been a definitive definition, but MANY by marketing
people who do NOT understand.

You can give some characteristics that might qualify a given hunk of
iron as having mainframe status, but there will always be an
exception.
If it requires special cooling (e.g. chilled water, liquid nitrogen),
it's probably a mainframe.
Well, these days people are building 19" racks for high density datacenters
with builtin water cooling at the rack level. And when you look at the
power density of e.g. a fully loaded blade system has it makes a lot of
sense.
Wouldn't call those setups mainframes, though ;-)
Kind regards,
Alex.
