Hairless cats are well known, and there are many mutations and morphs within species to remove fur from an animal, even in reptiles where you have scaleless snakes and lizards. Keeping that in mind it could be possible to breed a hairless Lion.

Seeing a Hairless mutation in Lioden could be a nice addition. Of course, there’ll be setbacks to the mutation, such as less strength due to enemies being able to pierce the skin easier.
The mutation would affect both males and females.
