Can I use the word "keep" instead of "hold" here?

In this case, to "hold" means to "grasp" or "carry," so "keep" (which means to "have" or "possess") is not appropriate here. However, you can use a synonym of "keep" instead, which is "have." You may wonder what the difference between "keep" and "have" is. They're synonyms, however, the definitions of "have" are much more broad. In this case, "have" means to place something in a specific position. "Keep" isn't usually used in that way! Ex: Why are you grasping your book like that? Ex: Why do you have your book like that?
