I dont think so, unless you bought it on Origin as a download(not the boxed version).
I had the same issue with C&C 3: Tiberium Wars, i contacted support about it and they told me that "older" games wouldnt be able to register with Origin, unless they where actually purchased as a download via Origin.
I got boxed versions of all C&C games, except Red Alert 3 - Uprising, and the only two i was able to register with Origin was C&C: Red Alert 3 and C&C 4: Tiberian Twilight.
Hope this info helped

I didnt think that you could get CnC: First Decade as a digital download. I mean it comes with a bonus disk that talks about the first ten years (1995-2005) of Command & Conquer being available to the masses to have fun with.
