The IP address will change depending on where it connects to, and the serial number may or may not get sent during updates (depending on the configuration) and would require a court order to force the issue.
There is software that can be uses to "phone home" when stolen, but like was said, can be deleted easily enough. Unless you took precautions in advance against such an incident, the laptop is good as gone. Sorry.
