My neighbor's got a leak in the hot water line running from the manifold
in her utility room to the kitchen sink. The copper line is in or just
bellow the concrete slab. The plumber has to dig up a substantial portion
of the kitchen floor to replace the corroded line. He's going to use
Copper. Wouldn't it be better to use PVC?

No. PVC cis not rated for hot water. PEX might be a better option though.
