According to page 275 of the National Academy of Sciences Food and Nutrition Board Dietary Reference Intakes for Energy, Carbohydrate, Fiber, Fat, Fatty Acids, Cholesterol, Protein, and Amino Acids, the answer is: No.
The human ability to function for long periods of time with no food intake at all indicates no absolute requirement for dietary carbohydrate. This ability is due to a metabolic capacity to adapt to using fat and protein exclusively as fuel (page 276 of the same document):
Thus it is accurate to say that humans have dietary requirements for fats and proteins, but no dietary requirement for digestible carbohydrates i.e. starches and sugars.
