-Can I take the key of my current computer's OS and put it into a new computer?



If so, how would I be able to do this without the new computer telling me that the key is already in use or that the windows 7 is not genuine?Yes, but only if you plan on uninstalling / changing the OS on the computer that you are taking the key from. Most licenses are transferrable to new hardware, but they may only be used on one computer at a time, so you cannot use the same key on both machines.

However, you will have to activate Windows on the new computer, there is really no way around this. If it doesn't activate over the internet, you can use phone activation. If the key is genuine, it's not likely to tell you otherwise.No, I don't believe you can.
