Will lead (Pb) react with HgSO4?

Yes — a reaction will occur because lead is more active than mercury.
Reason: In the activity series Pb is above Hg, so Pb can displace Hg2+ from solution. The reaction:
Pb(s) + HgSO4(aq) → PbSO4(s) + Hg(l)
(Lead is oxidized to Pb2+ and mercury(II) is reduced to metallic Hg; PbSO4 is an insoluble salt.)
