No - they are there to use as replacements should another button fall off.
ANSWER
No, I would not do that. The buttons are placed low on the garment where they cannot be seen, and you will always have them available if need be. If you were to take them off, there is always that chance you will misplace, or lose them. The only time I take them off, is when I am ready get rid of the attire. Never hurts to collect buttons that can be used on other clothing.

The spare tire should be inside the rear passenger side of the vehicle. Pop your hatch, remove the three plastic buttons holding on the passenger rear plastic hatch cover, where the speakers are if so equipped. The jack and spare tire should be under this cover.
AnswerAny buttons that are sewn onto the bottom of a dress shirt, are there in case any of the primary buttons get lost for various reasons. They're spares. There is no standard for how many spares are given, but there should be at least one for each button on the shirt. You're referring to one of the smaller ones and correctly noting that the collar isn't button down, so you believe there is no need for a small spare. However, if you look at the sleeves, just above the cuff, you'll likely see a small button that's designed to be undone so your arms can fit through the sleeve easier. Then, once it's through, you button that small button to keep your forearm from being exposed. The shirt may not have a button down collar, with small buttons, but the small spare at the bottom of the shirt is there as a backup for the small sleeve buttons.
Remove the cover in the trunk. Should be right there.
So if you loose one of the buttons you can sew a new matching one one.
