You should start reading the "Moving from Qt 3 to Qt 4" overview:
http://doc.qt.nokia.com/4.7/porting4-overview.html

In short, yes, you can, but the effort you have to consider (to port it) 
depends on your code... though I personally think that a _reaL_ Qt3-to-Qt4 
port would in most parts mean a rewrite of your code (NOT using Qt3Support) 
and getting used to Qt 4 and its new & interesting features.
