I would like to upgrade the cpu on my elite book 840, is that even possible?

Currently I have Intel Core i7-5600U 2.60Ghz x 2

Thank you

No you are king of the hill already. If that processor is not giving you stupendous performance something else is wrong. 

Let us know what issues you are having that you believe require a cpu upgrade.

I'm a web developer ans I rien multiple instances of various programs simultanouesly and the do a lot of compilation. They run a little slow even is I added RAM to a total of 16gig. So I thouht maybe the cpu is toped.

The i7-5600U is a low voltage processor so naturally runs a little slower than the standard versions but is as good as it gets for your laptop series. 

For the uses you describe I can see where you can use as much power as you can get. The only line HP would have that is more powerful would be something like the Zbook Mobile workstation series.
