FYI if you us ethe default error page as set in the cfadmin, you can use
cfml in here.
I have seen this cause problems though for the reasons Dave described, as
customers cause errors in the error and then blame it on the host/server.

That is correct. Your error page can't be a .cfm page. If it could, it
could in turn generate an error. This is basically a leftover from the
old days of CF - presumably, early versions would have sent the error
in your error handler to your error handler, and so on.

You can use CFML code to deal with compile-time errors and run-time
exceptions via the site-wide error handler (which can be a .cfm page).
You can also use CFML code to deal with run-time exceptions using
TYPE="EXCEPTION" in your CFERROR tag and pointing to a .cfm page.
Finally, you can use CFML code to deal with run-time exceptions using
the onError event handler in Application.cfc or using exception
handling within your code.
