For the most part, yes. Where their ranges overlap (70mm to 150mm) they will have the same angle of view, but the 40-150mm will have the smaller maximum aperture. The shorter lens will be at or near it's maximum aperture of f/5.6, while the longer lens will be at or near is maximum aperture of f/4.0. For that reason, you would be able to use slightly faster shutter speeds with the longer lens, all other things being equal.
