Is the water from lead water pipes also healthy to drink?

Answer

You’re right, lead is unhealthy. And in the past (already with the Romans) people have certainly become ill by using lead cups, for example.
Nowadays lead pipes are no longer used, I think it is no longer allowed.
But the existing pipes should therefore not be harmful. Water always has a certain hardness, if that hardness is too high it causes problems: coffee maker, washing machine, boiler, …
The hardness of the water creates a layer of lime on the lead pipes, so the water no longer comes into contact with the lead.
But the water will never be completely softened, then it will become too aggressive: the lime layer will dissolve and the lead can also dissolve (a little).

Hopefully this gives you enough information.
