Another potentially important difference is that when I play piano my hands move side to side as I play (the keyboard is very wide) which might spread things out some? Since I work standing up I could try typing while stepping left and right...
Not sure. There are other differences, too. – In the way the keys respond, and the fact that on a piano key you have much more freedom in choosing a convenient place for your finger. – This could all lead to less crampiness. So again, talking to an expert is the best bet. I’ve had good experiences with online PT consultations for weightlifting-related aches and pains.
Okay, that speaks against my hypothesis.
