from old age, maybe but also due to a chemical reaction between the paint and the varnish

They already suggested varnish replacement, didn't they?

sure, but will the reacted paint also disappear with removing the varnish?

No idea. If the pigment is not removed, its discoloration should not change. Selectively removing lead from the pigment can be difficult (although it doesn't have to be impossible, a lot depends on the exact composition of all substances involved).
