No. I am 99% sure it was only ever 1/20 and 1/40, as far as badging was concerned. They definitely sold other configurations as options but the badging was SE or SE/30 for the other configurations for those respective machines.
It was at least terminology Apple used, if not on the case. Macintosh SE 2/40 Upgrade: SIMM Requirements
Yup, terminology they used to describe the configuration, but not used on the case that I've ever seen evidence of.
