Yes, although roasting them exactly the same way is probably not a great idea. But you can roast them to a similar level. It can be quite a subtle difference, and part of the flavor might also come from the way they process the coffee before it gets roasted (washing the beans, letting them sit in the fruit a little longer, etc.) But I am sure many people can taste the difference between a costa rican and an ethiopian coffee, as long as it's not roasted to charcoal level. That might influence why people ask this question. A lot of coffee people drink is roasted so dark that there's probably no big difference anymore. Additionally it's often blended. I guess it's how you guarantee a consistent flavor (and bottom line).
