That is a spectacularly dumb thing to say.
Where is the evidence that Boris would be calling for prosecutions? During his campaign for LM did Boris hire a bunch of goons to go back through Kens history and dredge it for scandal ? (No, but Ken did that to Boris)
Has Boris launched any prosecutions for Malfeasance in Public office against Ken or his cronies ? (No but the Allegations made in the Evening Standard could warrant investigation)
So there is no evidence, you are just using school boy level debating tactics, "yeah but no but yeah, Boris would almost definetly, certainly, have done the same right so that makes this extraordinarily ridicolous prosection ok by me."
