Is it possible to display only one latest post from a specific category on the home page without the use of any plugin?

Without a plugin? Probably not. The default wpmu install doesn't compile the posts across the blogs. It just keeps track of the name and numbers of those categories.
Easiest method of doing it would be a sitewide tag system. Please do a search of the forums for a couple different solutions to do up a tag system.
