Companies that market computers may choose to use the term "notebook" for laptops that are among the smallest and lightest of their product line, but this is not an industry standard or a widespread practice.

Tablets are smaller and lighter than laptops, and the primary means of input is through a touch screen. While laptops with touch screens do exist, it is considered a standard and defining feature of a tablet.
