I always use root exploere to remove apps and it very easy. Just open RE and select system>app then locate the apk you want to delete then just long press and select delete app.
Sure, if you are comfortable doing that. I see way too many people who asking about rooting phones and such without the knowledge of the risks they are taking. I know this isn't that per-se, but it is similar.
Be sure at the top of Root Explorer that it is set as "Mounted as r/w" instead of "mounted as r/o" that ensures that you can change stuff, otherwise it wont allow you to delete stuff in your app folder
