If they're just in the finish, then no.
If the finish has cracked because of something bad happening further down, then there's all sorts of potential for nastiness.
Pics?

I haven't got any pics at the minute.
The plan was to sand the finish off and then put a laminate on the top to make it look lovely but some of the cracks have gone below the finish (I sanded the back off) and then below what I assume is a laminate as the wood underneath looks completely different.
