Not in the US. The Age Discrimination In Employment Act specifically only prohibits age discrimination against workers who are 40 or older. Discriminating against someone not over 40 is perfectly legal. More generally, discrimination in employment is legal by default. It becomes illegal only when a specific law gives protection for a specific characteristic. The laws are much narrower than many people think. For example, there are no laws disallowing discrimination for or against smokers, or Yankee fans, or D&D players.
