No. The license on the computer you buy is OEM. If you wish to use a retail license for the Windows 8.1 downloaded, you need to purchase a key for it.

You might wish to look at a Windows 8 compliant partition tool (several available) and partition that way.

Depends entirely on where on the Net you have found the download.  If it's one of the legitimate Microsoft downloads then yes it should work fine. The OEM activation code embedded in your laptop should be detected and activate automatically using the same version of 8.1 that was supplied.  You shouldn't get asked for an activation code (in fact if you do then the download doesn't match your system)

Make a backup of your system (full backup) and try it. I do not think such sites support OEM installs but I am not certain

That link still takes you to the Microsoft download site (you'll understand why you need to be careful about your download sources) - you'll end up with a file called 'mediacreationtool.exe' that will download a language and architecture (64bit) specific version .iso installer that you can either burn to DVD or put on a USB drive.  

The nice thing about the 8.1 Microsoft installers is they now also support embedded OEM activation with UEFI BIOSes
Reinstall just for repartitioning? Why?
agreed - it looks like there's no real need for that
you can repartition your drive in win8.1 from the disk manager
- in disk manager, select your OS partition - right click it, and select shrink to resize it to the size wanted
then you can use the free space for a new partition
but why do you want another partition ??
