Yes radio rooting will allow you to remove unwanted system apps, either use a root file explorer like Root Explorer and navigate to the system/app folder and delete the apk. You can also change the .apk part of the app to .bak, this way if you change your mind later you can just change the .bak back to .apk. Alternatively you can use an app like Titanium Backup, this has many handy root functions as well as uninstalling system apps.
Be warned though, uninstalling the wrong applications can result in a bricked device. I have uninstall the Oriental keyboards because I know they are not going to harm the system, just be mindful young one...lol
*Just for people's information, since ICS Google has incorporated the ability to freeze or disable most system apps. This means the app will remain in the system but is dormant, the app will not appear in the app tray and will not use any system resources.
Menu> Settings> Apps>
Select the system app you don't want and select disable at the top right, some apps may have updates in which case you need to uninstall those updates first before disabling the application.
