IanCP, Of course getting the answer from Google - and having it be authoritative would be ideal. But there's two catches: first of all getting them to answer is not that trivial, and getting them to answer to the point is far from trivial. Usually all you get a pre-chewed answer - missing the point of the question itself.
The second catch is even worse: adsense support has been known the repeatedly give advise -even unasked for- that later was used as infringing on adsense rules by those that enforce the rules (obviously not the same that do the support). Iow: they are not authoritative.
To me it's clear "you" defines a person entering in a contract. If you have a stake in another legal entity (a company, e.g. a ltd), "you" as a person and "you" as the business are different by law (out where I live at least).
Still if you keep two accounts - one yours and one from a company, even when they are well and clearly not both "yours" in the legal term, you better separate them out 100% (down to from where you connect to them) unless you want their fate to be linked as associated accounts.
If you do not have a different legal entity: all bets are off and you're going to be subject to Google's goodwill no matter what answer you might (or will not) get. It's unlikely with their current enforcing that they'll track you down. At least not until one of your accounts gets in trouble - maybe not by your own doing, all that might be needed is a click campaign by a jealous competitor - and both your accounts might be in deep trouble. The depth of the trouble then might become deeper due to having multiple accounts and the road to recovery even harder.
So I'd advise against it and just using one account only unless you have no other way - and by then you should have separate legal entities. Just make sure to split them up for 100% to be on the safe side and not let Google associate one with the other in any way - not easy, don't check your gmail on both computers you use or they know you're associated.
