Can I go to Malaysia to obtain a Tourist visa after extending my non-immigrant B visa in Thailand?

Without seeing the stamp or wording two things come to mind. Either the office made a mistake and gave you a month, or they gave you an under consideration stamp. Either way it doesn’t matter to your original question. You can get a tourist visa at a nearby consulate and come in as a tourist. Beware that some nationalities will have difficulty doing so and may only be able to get one in their home country.

Can you post a picture of the stamp or tell me what the wording actually says? My guess is the it says something like “application under consideration” return on xx/xx/xx
