I see that Microsoft has a utility that (apparently) can read a running system and create an image that can then be imported and run on Virtualbox.

"You can even have Disk2vhd create the VHDs on local volumes, even ones being converted (though performance is better when the VHD is on a disk different than ones being converted)."

Is there anything that does the same thing for Linux, and can image a system like that while it's actually running?

I doubt CentOS has anything for virtualbox, you should check with Oracle there.

But you can use virt-p2v to create a KVM image. It needs to be run from a rescue disk or livecd though.
