I'd like to change the google account an unrooted Nexus One is linked to without wiping. If I try to remove the current account it says it can't do it without a factory reset...
That is correct, you can't change the primary account without a wipe.
However, you can use Titanium Backup to back up your apps and settings so that putting your phone's environment back together after is a snap.
