We need to remove or move hadoop/yarn/local appcache or file cache which is taking lot of space .

Is there any impact while using applications which uses hadoop if we remove or move appcache or file cache ?

You shouldn't move the directories under hadoop/yarn/local while the NodeManager service is running as it will affect running application containers. Stop the NodeManager service on that node, perform the move operation and then start it again
