Just don't do it. If you are creating a startup, particularly if it is in any way related to your current work then the clear answer would be to never use any work computers in any part of the startup. Your workaround of just remote desktop'ing into your machine is not a good idea. Personal emails is one thing, but if you use your work computer for emails that are part of your other startup then you are tainting your new business.
