Short answer: not reliably in v5.0

Details: 
when you write::

   _constraints = [ (_check_vat, ...) , ... ]

you mean that *the exact visible instance* of `_check_vat()` is used. The one 
that exists in the same file! So, if you redefine a `_check_vat()` in a 
subclass, it won't work.

If you had::

	def __check_vat(self, ...):
	    # dispatch to another function
            return self._check_vat2(...)

	def _check_vat2(self, ...):
           # do something

then, you could possibly override the `_check_vat2()` in a subclass and let 
that be called instead.

The problem with 5.0 is, you cannot deactivate the `_constraints` line in an 
additional module (addon), without hacking the base (official) module.
