Yes, they at least certainly did on the Defender 90 series.
The problems with those vehicles (and all applications where steel surfaces meet with aluminum surfaces) is that the materials do chemically react with one another, especially when exposed to salt and water. Defender 90s seem to have interesting rust problems where steel meets aluminum.
I think that this Ford concept will work, but there are going to be issues with ownership of these vehicles. I expect most noticeably if bodywork is ever needed. You really can't repair mangled aluminum, only replace it. All in all that's probably not a huge issue.

If Ford treats the owners of 150s like Nissan treats Leaf owners, there will be a clause in the Warranty excluding damage from driving on salted roads.
