Pretty much yes. A hair dryer won't cut it, a heat gun the type you strip paint with should or a mini blow torch. When using direct heat be careful of the coating/finish, basically the heat required to expand it enough shouldn't get anywhere the near point to damaging the surface.
Put a nipple spanner on the nipple as you apply the heat and slowly apply pressure, it should just undo. Don't be tempted to over heat, you may need to repeat a few times, cool the area after each attempt with water. It's also possible it won't work or you strip the threads from the caliper body which is always a risk.
