From Wikipedia: A continent is one of several very large landmasses. Generally identified by convention rather than any strict criteria, up to seven regions are commonly regarded as continents.
Always thought a continent was a clearly defined.

Plates with large land masses are the Eurasian, Australian, North American, South American, African, Arabian, Indian, and Antarctic. The Caribbean plate has part of central America and several large islands on it, the Pacific plate has a number of large islands like Hawaii (and part of New Zealand), the Cocos plate has the tip of Baja California, and IIRC the remaining plates have only small islands (Filipino, Juan de Fuca, Nazca, and Scotia plates).
So by a definition of "tectonic plate with large landmass" you'd get at least 8 continents.
