Probably - but I wouldn't
Material Type: Plastic
This is not very informative, and i couldn't find any details. If there is a food safe symbol on it, it shouldn't introduce any toxins to your food in realistically expected use cases. Including common accidents like unintentional boil of your mash. And there is no real difference between accidental or planned boil, is it?
At the same time, it is mash paddle, so it may get less stiff and strong over mash temperatures, say, 180°F. If parts of it will tear off? No one will blame manufacturer. Still, your wort shouldn't be in any danger of contamination.
You may try to boil pure water, and see how it acts. Or leave this one for mash, and buy big wooden spoon for boil. These are pretty cheap, and safe.
If there isn't a food safe symbol, consider throwing it away.
