No.

Would that cause any problems?

Yes, the stock rules make use of code from EvalTests.pm. The functions available
through that file are not the same in 3.0.4 and 3.1.0.

So upgrade. You'll not only get the stronger rules, but you'll get the code
improvements too.

Often times code improvements (changes to the HTML parser, etc) have a more
dramatic effect on accuracy than changes to the rules alone.
