Hi Chris,
There is no way to make a grouping a link. In the Task Report you mentioned, to make it easier to navigate to the project, I'd add the column Project Name to the view. it will be redundant for Tasks under the same grouping, but it is the only dynamic way to have a hyperlink to the project of the task
