In the US, I think shorts can be used to mean underwear. Generally, in the UK, you would have to be more specific - boxer shorts - to differentiate from the type of shorts you simply wear in the summer because they're cooler!
There is also a difference in meaning between the USA and the UK with pants. Trousers in the UK are pants in the USA. Pants in the UK are underwear (men's and women's, althoug women's are regularly called "knickers"). I'm not quite sure what the AmE word for women's underwear is (possibly panties?)
