Yes — but the products are KOH and H2, not K2O.
Balanced equation:
2 K (s) + 2 H2O (l) → 2 KOH (aq) + H2 (g)
Potassium is very reactive with water: it is oxidized to K+ (forming hydroxide in water) and reduces H2O to H2 gas. The reaction is strongly exothermic and can be violent; K2O forms when K burns in O2, not when it reacts with H2O.
