I would probably advise consulting a qualified attorney to discuss the level of risk you're willing to accept; I expect Linode will not hesitate to comply with properly-executed warrants, at which point you'll probably want to have that attorney's business card in your wallet.
In other words, this is a legal question, not a technical question.
(Also, having worked on an abuse desk before, I suspect you can save a lot of time by just saying "<<insert Tor abuse boilerplate here>>" instead of copying/pasting the entire spiel; they aren't stupid, everyone knows what Tor is, and that won't answer the complaint.)
