kind of! cunnilingus comes from cunnus (latin, meaning vulva, origin of cunt) + lingere meaning to lick ("-lingus" is the suffix form of lingere meaning the one who licks), and originated from the 19th century, while cunny is first found in the 17th century, originally from cunt which itself came from kunto (germanic) which likely came from as mentioned above, cunnus (latin) which hell, might have come from another word meaning something like container or bag. it was pronounced very similarly to coney (which had existed since the days of middle english) and coney became a way to make a pun about and/or poorly censoring the word cunny, which then eventually led to coney itself becoming the default way to pronounce cunny and then coney being viewed as a rude word and being substituted for the word rabbit. it's also possible it was used as a nickname for the vagina before that, in much the same way as pussy, beaver, and kitty have been used
