Worked in a few houses where both water pipes and cables are run behind the skirting and also behind the door frame arictrave, you have no idea its there till it goes bang or you have water pouring out.
House a few months ago had a cable coming out of the wall and buried behind the skirting board that also had dry rot, so needed replacing, the cable was live and no plug socket attached to the live tails, luckily i saw it just before i crowbared the rest of the skirting off.
If you go ahead, youll know its ther but nobody else will know, and it may well injure them or kill them if they ever drill into it.
