I would say yes. Do short tasks during the weekly review.
You should ideally do all 2 minute tasks during the Process stage if your following GTD to the letter not during the review stage. That said the 2 minute rule is a fundamental of GTD so I'd probably extend this to the review stage if you find your still left with tasks.
Here are my tips for things you should consider during the review stage...
Identify any tasks you can complete in under 2 minutes. Do all outstanding tasks immediately - even during review. If you find it's taking to long to complete all the tasks if you leave the review for one week consider performing 2 reviews each week.
Eliminate tasks you've completed
As you complete tasks in your GTD Next Action lists be sure to mark them as complete or move them from your Next Actions list. As Next Actions shrink bring in more tasks from your other projects or some day lists to complete next.
Reorganize your tasks as you complete tasks or priorities change
As new ideas and tasks come to you during the day you'll probably find yourself adding these into your favorite task management tool. It's important to organize everything you capture during the day into your lists during the daily or weekly review stage. When organizing your tasks consider filing or moving everything you can't complete right away or in under 2 minutes into your "Projects" or "Some day" lists.
Keep your lists short and motivating
It's liberating to dump all your ideas or tasks into a task management tool but you should ensure your "Next Action" list only really contains the things you need to focus on next. Spend time to organize everything else neatly away within your Projects or some day lists during your reviews.
BTW: I recently launched a new task management tool (in beta). Shameless plug I'm sorry but you may get some value from this if you don't have a formal method to manage your tasks - you can check this out here https://www.wuudo.com/
