Obviously you may classify your lenses any way you want but there are commonly accepted terms that you can't change. Here is a definition of telephoto lens from Wikipedia:
---------------------------------------
In photography and cinematography, a telephoto lens is a specific type of a long-focus lens in which the physical length of the lens is shorter than thefocal length.[1] This is achieved by incorporating a special lens group known as a telephoto group that extends the light path to create a long-focus lens in a much shorter overall design. The angle of view and other effects of long-focus lenses are the same for telephoto lenses of the same specified focal length. Long-focal-length lenses are often informally referred to as telephoto lenses although this is technically incorrect: a telephoto lens specifically incorporates the telephoto group.[2]
Telephoto lenses are sometimes broken into the further sub-types of medium telephoto: lenses covering between a 30° and 10° field of view (67mm to 206mm in 35mm film format), and super telephoto: lenses covering between 8° through less than 1° field of view (over 300mm in 35mm film format).[3]

iPhone 7 lens does not fit this definition. Having a 2x optical zoom is a very good thing but let's not get carried away and buy the Apple PR without critical thinking.
LOL @ you trying to apply DSLR definitions to a smartphone camera module.
It's 56mm equivalent, f/2.8 on a 1/3.6" sensor. With OIS it would have good low-light performance for a smartphone, so I'll wait another year for Apple to add that obvious feature.
All else is marketing. Doesn't matter what you call it, the 56mm equivalent focal length is fixed.
