Yes, you are correct in assuming that 310.10 could be used to enforce voltage drop.
310.10 states: "Conductors shall have sufficient ampacity to carry the maximum load without exceeding the conductor temperature ratings."If a circuit has low voltage, it will cause current to rise in the conductors. If the current exceeds the ampacity of the conductors, it will cause the conductors to overheat. This can lead to a number of problems, including: Reduced efficiency of the circuit Damage to the insulation on the conductors* Increased risk of fireIn order to prevent these problems, it is important to ensure that circuits have sufficient voltage to operate properly. This can be done by using voltage drop calculations to determine the amount of voltage drop that will occur on a circuit and then selecting conductors with an ampacity that is sufficient to carry the maximum load without exceeding the conductor temperature ratings.
