Yes, you can travel to other Schengen countries with a valid Norway Tourist Visa. Since Norway is part of the Schengen Area, the visa allows you to visit all other Schengen member countries during its validity period. However, you must follow the 90 days within 180 days rule. In most cases, Norway should be your main destination or first point of entry if you are applying through the Norwegian authorities. The visa does not allow travel to non-Schengen countries without a separate visa.
