Sure, it's entirely possible! They're just rare inside the core of the hurricane, but both have been detected before. The updrafts in a hurricane are not as powerful and spread out over a wider area than in a thunderstorm, which inhibits the ability to create lightning and hail. Furthermore, the freezing level inside the warm core is very high, which cuts down on hail formation. If you're in the outer bands of a hurricane, you can see hail and lightning from thunderstorms more easily.
