I don't see that would work... Plus, if it were possible, I would think a company would utilize that for marketing leverage to appeal to more users with only the older mDP cpu's.  In this case, that's not what is happening.  So I don't believe it will work like that.  Typically, a company wouldn't make specific statements (ex "attaching to any Thunderbolt enabled device"), if it was Not a requirement to work.
Then... on the technical side of it...
The TB cable / signal is a (new technology) Muxed signal of both PCIe and DP data.  Without the TB chipset / hardware on the host machine, it can Not communicate properly down the Thunderbolt cable and to any TB device.
As you can see in the cable cut-away... it's NOT just a matter of adding individual DP lines along with some individual PCIe lines and wrap it up in a single cable.... where you can choose just to use only the DP lines.  Nope... this is highly improbable and suggests that using an OLD (non-TB) computer will NOT work at ALL, if connecting to a TB display or any TB device.
