No, it's markedly smaller. The original AES was a monster. Width of the original TG16 in 235mm, AES is 325.
I'm pretty sure the controller is the same size, but the console itself is much smaller.
Couple of questions: #1 Do you think the SNES, Genesis, NES and PlayStation (and Atari Flashback X, if you've seen it) minis are all to the same scales?
Second, what would the proper size be for a TG16 and Neo Geo AES at the same scale as the SNES Classic?
