I don't know about 4 hour, but there are guys on this forum successfully living the mobile lifestyle. More realistic, though, is putting in close to a full workday. Especially if you have a service business. If you have a product business, then the "4-hour workweek" may be more realistic after a lot of refinement to your business process. And as someone else said, starting up a product business is pretty much a nightmare in terms of the work involved. I think of it like a marathon. Have enough stamina, and you'll get there.
