If your product key has come from a legit source, that question should not arise.
I ask this question as I have four machine all with OEM Windows Key, and I don't have the OEM CDs.
There should be a COA sticker on the side of each machine (The sticker is your key) , If you have four different stickers, one on each machine then yes you can use one Windows 7 CD. Just install windows 7 on one computer at a time matching the right key to the computer windows is being installed to. Also you may have to visit each manufacturers site to obtain drivers
specific to each model.
