In a camera, the lens is close to the film/sensor and relatively far from the objects being photographed. The first requirement for use in an enlarger would be to mount the lens so that the side that is lose to the film/sensor in the camera is close to the film or slide in the enlarger. Then, if the lens is any good for photographing subjects at a close distance, i.e. the typical height of the enlarger head, then it should be equally good in the enlarger. Perhaps enlarger lens mounts normally accommodate camera lenses in this reversed orientation. Not having ever put a camera lens in an enlarger, I just don't know.
