No. In simple terms, you use 'fewer' for things you can count, and 'less' for things you can't. For example, the Tories could win fewer than 100 seats, which would mean they would have less political influence than before.
The key thing is whether you can count it or not. If you remember that simple rule, you will make fewer grammatical mistakes and you will be less wrong.
