I've tested this with both Cricket and AT&T on my Lumia 1520 and it's working great. I'm assuming it will work with other carriers and phones but would need to be tested. It requires registry editing capabilities. I used the CustomPFD registry editor with it running as the Preview for Developers app. (note: I had to use this method to get registry write access)
Basically you just have to set the following registry keys. For carriers like Cricket that completely blocks tethering you'll need the ICSSVC & system settings but for others like AT&T that allow it but only on certain plans you'll only need the ICSSVC settings.
Note: dword:000000b0 is integer 176. Also, if you change sims this will get reset and will need to be redone. I've seen vague references to some of this info but never a good writeup so hopefully this helps other people.
