No, Wingardium Leviosa can only be used on non-living objects. However, there are other charms like Levicorpus that can be effectively used to levitate a person. Furthermore, Wingardium Leviosa can be used to levitate objects around people, including their clothes which, if they are wearing, will technically levitate the person as well. However, the effect of levitation is felt only on the clothing and will therefore probably be very uncomfortable for the person being lifted.
