Two Product Keys for Two Consecutive Years

Hi everyone, I was wondering if somebody can help me with this. I got a real good deal on purchasing Norton Security Premium (10 Devices) with Backup, so I decide to buy two. 

My question is can I use those two product key codes (Norton Security Premium with Backup) for two consecutive years, meaning of I use one product key code for 2017 and use the other product key for 2018?

Thanks for your help with this question.
