Would a Nvidia GeForce GTX 870M fit into a Hp Probook 640 G1? By changing the Gpu and motherboard

No. That's an mxm card. Very few PCs can take them, and from my look at your specs it does not have an mxm slot.
Please don't even think about changing a notebook motherboard. They are highly customized to the model.
