No. ALL floppies were called "diskettes" because they were tiny compared to hard disks, which were the usual sort of "disk" up until IBM devised the floppy format for loading boot code into their mainframes.

Sauce: My dad had a Tandy Model 16 with 8" drives (of the Shugart Thinline variety, one of which is pictured in the article!). Tandy sold blank 8" media that were labeled as diskettes. In addition, when the computer booted, if it could not detect a boot disk it would turn the screen white (green) with the words "INSERT DISKETTE" in the middle.

In addition, IBM referred to the 8" floppy format as the "Type 1 Diskette", which nomenclature dates from 1973.
