In a Hollywood movie, sure, with obligatory leading warrior woman role. In real history, not so much. With very rare exceptions (like England [1], and some Eastern European lands were at least some of peasants were militarized) peasantry had little military value [2], and therefore little factor in any rivalry. Also feudalism had more strict rules in regard to competition for resources compared to modern criminals. A rival had to appear first, and in most cases needed to have rights at least somehow proven by genealogical tree, and old agreements. While it did happen, it couldn't just because of peasants.
