If you pay for your internet access, what difference does running a computer over clearnet make? Your ISP knows someone is running Tor connections out of your home either way, or at least they can know if they bother to look. You might still have some plausible deniability in that you could be allowing a friend to access Tor from your home, or someone is stealing your wifi. Are you saying it's less deniable if the two forms of connection happen simultaneously? I doubt any of this matters in a court of law, since it could happen at the same time or different times. In any case, so what? Using Tor doesn't prove you're doing anything illegal. And accessing clearnet on a separate physical computer won't reveal your identity to the sites you are visiting over Tor. That's why I was said it was zero risk.
