I think "ALU can add up to n-bit numbers" is a reasonable definition
for an n-bit architecture, which also fits the 16-bit 68000.
It does not fit the 360/30, or the Nova (but see de Castro's remark
on the latter).
To me, the phrase "n-bit architecture" should depend only on such
characteristics as are defined by the architecture, and not depend
on features of a particular implementation. The 360/30 has a 32-bit
(or is it 64-bit?) architecture, but only an 8-bit implementation.
If I may add a personal note, it's disappointing that postings in a
group nominally devoted to computer architecture routinely ignore
the distinction between architecture and implementation. I don't
mind comments about matters of implementation, but the constant
blurring (or erasing) of the line between architecture and
implementation often makes it nearly impossible to have a discussion
just about architecture.
