Yes, this is possible with advanced methods of FUE. FUE uses head hair as a donor source so if there is an adequate supply, hair can be transplanted to the leg. There are also two additional options. Body hair transplantation (BHT) uses non-head donor areas for grafting hair follicles from the chest, stomach, arms and legs. Facial hair transplantation (FHT) is when facial or beard hair is also used. This advanced transplantation requires more skill and precision than other FUE methods since body, facial and head hair vary greatly. Facial hair tends to be the highest caliber of body hair, with beard hair typically providing the greatest yield regarding long-term graft survival. Keep in mind facial and body hair acts and looks differently than head hair. It remains the same in terms of growth and volume. However, an experienced surgeon understands the innate characteristics of body hair and makes placements accordingly. In this link you would find an instance from six years ago where I used thigh hair to replenish leg hair loss in a past patient of mine.
