Do you mean re-use them to inhale the other tabs?
Probably not as the copd drug is specially processed to make it Micro-dispersible . The drugs I am prescribed for copd is measured in micrograms. If you were capable of processing your tabs to such a small particle it might, but the trick is getting the tabs cruhed, then coated or processed is some manner that they stay "Micro-dispersible " so they can flow through the inhaler and into your body.
From my research it's a fairly complicated and expensive process that was actually developed for biological warfare, then re-applied to medicines.
