First off, if there is available space on the drive in your laptop (or another partition that you can delete), installing another version of Debian should be without problems. I have a couple of different distributions on my desktop, and installing a new one or installing over an already existing one has never been a problem, as long as you set them all up to use GRUB. Second, virtual machines these days are incredibly easy to set up and use. Steve Litt posted a link to an introductory article on qemu/KVM here very recently, I suggest that as a starting point. There is a tool called "Virtual Machine Manager" (package: virt-manager) that I would recommend. It is very easy to use, and uses qemu/KVM. Virtualbox from Oracle is another alternative, though I prefer KVM. Using a VM takes a little bit of resources, but would give you the ability to run another distribution without having to reboot. You can run it full-screen, so you can use the desktop just as you normally would. For increased performance, you can set the virtual machine up to use a partition (or logical volume) just as a regular installation, instead of using an image file. It is at least something to take into consideration, as you could then have as many distributions as you want and have the resources for, running simultaneously.
