Her torso height would be the deciding factor, but even then I wouldn't wager a guess since you really need to get a kid in there to know for sure.
I make no secret of my love for the Coccoro, but I wouldn't buy one for a 2-year-old. Yes, she might fit now, and might for a while, but she won't last NEARLY as long (RF or FF) as she will in other comparably-priced seats.
The Coccoro is a great alternative to an infant seat, as a travel seat, etc. But after a certain point, it's not a practical choice. It's definitely not the last seat you'll need if you want to keep your kid RFing longer.
I know I'll need to buy another convertible to keep my DD RFing once she outgrows the Coccoro RF.
