Yes, although it won't be as flavorful where the rice will not have had the benefit of cooking in the flavorful broth. That said, it's still tasty! Reduce the broth by about 2 cups (500 mL) to make up for the broth not used to cook/rehydrate the rice. The cooking time will be reduced to only 5 minutes, or until the carrots and celery are cooked. Add the rice when you add the kale at the end.
