Just curiosity, does the word "luncheon meat" was originated from "lunch(luncheon)"?

Yes, that's correct! "Luncheon" is the formal word for "lunch" in English. Although "Luncheon meat" is used more often than "lunch meat," we don't typically use "luncheon" to describe lunch unless it is for a very specific, formal occasion. Ex: I was invited to a luncheon party by the mayor. Ex: I enjoy eating luncheon meats like corned beef and Spam.
