Cats can develop lumps on their backs for a number of different reasons. One of the main culprits of soft, squishy lumps under the skin - particularly in cats that are around other animals or go outside - is an abscessed bite wound. Abscesses are basically pockets of infection and require veterinary treatment in order to properly drain and flush them, and to prescribe antibiotics. I'd recommend taking Leo to his vet for evaluation to get to the bottom of this lesion so that treatment can be started promptly. I hope that he feels better soon! https://www.petcoach.co/cat/condition/abscesses/
