Not literally, no. The literal Lingua Franca spoken across the eastern meditarranean was named for the "Franks", which simply meant "Western Europeans" to the people speaking in lingua franca; but was mostly based on Italian, with slavic and Greek influences. So the French, the Prussians, the Venetians, probably even the Polish were "Franks" in the sense used in Lingua Francia.
In turn, the use of the term Frank to refer to western europeans was in relation to the Frankish Empire, a confederation of germanic tribes. France is one descendant of the Frankish Empire, Germany being another. The Franks themselves spoke a germanic language.
