Aside from the Apple TV controls not being very comparable to a usual remote, this link seems to indicate that it's possible:

Specifically (although not specifically enough), it says:
"I successfully configured my Rogers UEI brand HD PVR remote to work with my Apple TV box using the instructions provided by Apple so that when I press the white AUD key (located along the top to the left of the TV and CBL keys) the keys on the remote work like the Apple TV remote. However I could not get MENU or OK|SELECT keys to send any signals to the Apple TV box so I configured the VOL+ and CH+ keys as those keys respectively. I tried using VCR and DVD instead of AUD but that didn't work either. Has anyone had the same problem? For some reason the MENU or OK|SELECT keys seem to be disabled unless you choose CBL. Still better than having to switch to the Apple TV remote to control Apple TV but it's annoying that I can't use the keys that are labelled as such. "
So, this is not an Innovage remote, but apparently there are "instructions provided by Apple"
Another forum specifically for the Innovage remote didn't mention Apple, but did mention a "code search" function for another application, it could work maybe in my case:
"To have the remote try each TV code it knows one at a time, follow these steps: Turn on your TV. Press and hold the CODE SEARCH button for at least 3 seconds until the red LED lights up and stays lit. Press the TV button on the remote so that the LED blinks once and then remains solid red. Press the ON/OFF button slowly and repeatedly until the TV turns off. The LED will blink once each time you press the ON/OFF button. Once the TV turns off, press the ENTER button to store the code and the LED will turn off. To program the remote for your VCR, repeat this process starting with turning the VCR on, then follow the steps substituting the VCR button for the TV button. I hope that helps."
Ah, here are the "instructions provided by Apple." This seems as easy as pie to try out, apparently the Apple TV box can "learn" from any remote:
