What happens when dilute tetraoxosulphate(iv)acid is added to magnesium?

We've been down this road already. There is no tetraoxosulphate(IV) acid. The Roman numeral is VI, not IV. The Roman numeral gives the oxidation number of the sulfur, and in H2SO4 sulfur has an oxidation state of +6.
You can see why this "new" naming scheme from the IUPAC never caught on. If you're bright enough to make sense of "tetraoxosulfphate(VI) acid", then you are certainly bright tnough to remember the formula for "sulfuric acid."
As for the reaction of H2SO4 and Mg, Michael covered that nicely.

Magnesium reacts with dilute sulphuric acid to give magnesium sulphate and hydrogen gas.
magnesium + tetraoxosulphate acid [aka sulphuric acid] —> magnesium sulphate + hydrogen
Mg(s) + H2SO4 (aq) —> MgSO4(aq) + H2(g)
