No you cannot uninstall VirtualBox completely by simply dragging it from the Applications folder to the Trash. Although you can do so for most applications, VB is a bit more complex than most, and needs to install into other places (in particular it includes a kernel extension, I believe).
However, there is an uninstall too in the distribution. If you no longer have your original download, get it again, and have a look inside. You'll find the tool, "VirtualBox_Uninstall.tool" (at least for version 1.4.1).
Having said that, if you just drag it to the Trash, it shouldn't be a problem. The kernel extension will still be there, but shouldn't interfere with anything. But best to uninstall it properly to be on the safe side.
