The key is the differentiation between "work" and "business". Imagine I'm a website designer, or a copy editor, or a software developer.
Notice that all of that can involve a laptop and someone local -- that's not what's relevant in whether something is permissible or not. Business is allowed on a business visa. While it is not allowed on a tourist visa, many countries have a single "visitor" visa that covers both business and tourism. Work is only allowed with a work visa or work permit.
