Yes. user.cfc's updateUser() method can call person.cfc's
updatePerson() method since updatePerson() is inherited into user.cfc
instances.

A cftransaction can only enclose inline code, not any functions called
inside that code:
<cftransaction>
... bunch of code with no function calls ...
</cftransaction>
That will work just fine. The following will not:
<cftransaction>
... some code ...
callAnotherDatabaseMethod()
... more code ...
</cftransaction>
Any database activity in callAnotherdatabaseMethod() would not be
rolled back if you tried to rollback the cftransaction shown above.
That would impact you if your updatePerson() method did database stuff
*and* your updateUser() method did additional stuff and you wanted to
commit / rollback the combination of actions across both methods.
This seems to be bug #49953 and my guess is that you won't see a fix
for this for quite a while (but I'm willing to be corrected by Phil or
Debbie or...!).
