Personally I’d try a hair dryer with a plastic scraper. Is it a paper, plastic or metal sticker?

I am actually not sure about the material. Either plastic or paper. It is a white label at the bottom of IBM model M keyboard that I recently found in a local recycling center.
I don't own a hair dryer. Would my heat gun be too hot for it even at 100C?

I use a heatgun at a healthy distance that I know won't melt any plastic or brown/char paper and then use a razor knife to lift the sticker up, sometimes adding more heat.

What temperature you set the heatgun to? Would the thin nozzle that I use for electronics be good or better to remove the nozzle and blow air to a wider area?

The heatgun is an industrial paint removal thing with only 350 and 600ºC settings, which is why I said "healthy distance". I don't use any nozzle on it as it would make a heat laser which I don't. Heat cannot be much above 60 or you risk damaging any plastics etc.

Use a hair dryer. A heat gun makes no sense when dealing with plastics, it will just cause damage.

Perhaps heatgun was wrong word to use then when I talked about it. This is what I use and you can change the temperature of the air that it blows between 100C and 600C at 1C increments. I don't own a hair dryer and I would not want to buy one just for this if possible.

I wouldn't use a hot air soldering gun. Even with the largest tip on it, you are going to be concentrating the heat way too much. You need something that can heat up the whole sticker in order to loosen/melt the glue so you can remove the sticker.

What about borrowing a hair dryer?

Do you have any thrift stores near you? If so, hair dryers are usually really cheap at thrift stores.

Diameter is bit about 22mm when I take the whole nozzle off and then at lowest temperature setting I can blow air to my hand from 15cm distance without it burning my hand.
If that doesn't work I could probably borrow a hair dryer, but it would probably take over a week before I could get it.

You set that heatgun to 100, maximize airflow, put your finger on the sticker and move the gun to a distance where you'll have hard time keeping your finger in place. Now you will not damage the plastics and sticker and can start sliding razor knife under one corner to peel the sticker up.
