No for two reasons.
First, your laptop hard drive instance of the operating system almost certainly has the wrong drivers and such for the motherboard on the main computer. It would not boot. This can be fixed with either a repair install or using the Restore to Dissimilar Hardware feature of something like Acronis True Image, but...
Second, if any of the software is commercial ware licensed for use on a single PC, this would be a violation of the license and 1) unlawful, 2) something we don't allow on Tom's. I suppose that it's possible that all you have is open source software or multiple-seat licenses, but please check before considering this.
