My bad...just saw that. Airplane mode is not one of the toggles, but...if Sprint allows for the change of notification toggles, once they release 4.1.2, you'll have the ability to change those.
If you want to temporarily add some notification toggles, I actually use Widgetsoid for some apps that I want toggles on for 3rd party apps. It works great for my needs, so you may want to check that out. You can customize the colors to match (as closely as possible) the Samsung toggles.
So, to answer your question (bottom line), no...you can't currently change the OEM toggles on the Sprint version of the Note 2. If you want to get to Airplane mode quickly, just hold down the power button and there's a selection for Airplane mode.
