I have no doubt you could get it to run. Arc is just a thin layer on top of Scheme. The question is whether or not it's prudent to run any Lisp on a security device. I'm as big a Lisp fan as they come (look at my handle!) and running Lisp on an HSM makes me a little queasy.

My back-end server is using Clozure Common Lisp, and I certainly believe in using Lisp to cross-compile code for the HSM. There are a lot of ways to leverage Lisp besides actually running it on the device itself. But I have a lot of other Lispy tricks up my sleeve. Stay tuned!
