Theoretically yes. The Lion and leopard both belong to the panthera genus. There is one report of a large male leopard mated to a lioness in 1912 and produced 2 cubs (http:/wwwzperiodzmessybeastzperiodzcom/genetics/hybzhyphenzleopxlionzperiodzhtm). There have also been reports of Leopard/Jaguar hybrids mated to lions. Jaguar/Lion hybrids are more common as a male jaguar is similar in size to a lioness (http:/wwwzperiodzbearcreeksanctuaryzperiodzcom/jaglionszperiodzhtm). Leopard/Cougar hybrids have been sucessful as well but the animal usually possesses dwarfism. Due to the size difference in Lions and leopards it makes hybridization difficult but it has happened. Here's a picture of a Lion/Leopard Hybrid in Japan (http:/fauvesdumondezperiodzfreezperiodzfr/hybride/hybride_fichier/japanese_leoponzperiodzjpg)
