You probably can using a plugin that you'd have to make yourself, read up on the documentation if you want: http://codex.wordpress.org/Writing_a_Plugin

Or, even if I'm about to do a shameless self plug; my project FractalBB has some of the features of WordPress (Blog etc.) with the addition of a UCP/ACP and a not so feature rich forum system. It's very much a work in progress however take a look at it at least!
