Why couldn't he? I would say the people who insist Lando must be othered in this way are the people who are being weird here, not the people who used yellow for characters whose race didn't matter to them.
Why not? Did anyone try mocking it up? His facial hair would show up fine against yellow. If the white characters were recognisable with yellow heads, why wouldn't it work for him?

This feels more like virtue signaling than any kind of reason: This kind of logic lets you forever find new kinds of racism that you can then make performative fights against so that you can ignore real issues that plague the world.
Take these images, how recognisable would any of the characters (those with hair) be with different hair?
