Probably. But you would probably have to replace the power supply and add some components to the logic board. The CUDA chip 343S0780 (IIRC), a little sixteen pin (again, IIRC) SOIC controls the start up circuitry on those machines, I think. I'm pretty sure it's present on the 6100, 7100 and 8100, so the 6100 is not missing a major component. However, there may be some loose components, like logic gates or transistors that the 6100 lacks.

If I were attempting such a modification, I'd start with a comparison of the 7100 and the 6100. But again, you'd need a different power supply. Something like one of the Sparkle ATX supplies might fit.
