First sentence of that link says the IC is designed for the range of frequencies the mod enables. I'm not doubting that you can take an IC made for a given frequency range and use it in that range. Obviously this is possible. In the most extreme case you could just desolder it and hook it up to a better designed circuit.

The issue here is that the IC is apparently not rated to work above 108MHz, and although I haven't studied the manual in enough detail to say that it doesn't secretly allow higher frequencies with the right firmware patch, I do think that its not possible to somehow physically mod it to tune a wider band.
