There will not be any conflicts, but it will be good if you don't use the same.

Yes, you can use the same view model between views. A view model is just a class, and a view model's intent is to represent the data elements that you want to display on the screen. If two views have the same data elements, then it certainly could make sense to share the same view model.

Now, you have to be careful regarding changes to the view model class. Since you might be sharing this class, changes for one view could cause changes to the view model class. This may or may not have an impact on your second view. For example, if you rename a property on the view model, then the 2nd view needs to refer to this new name if it is using that property. If you add in a new property, but the 2nd view doesn't use this property--or remove a property that the 2nd view isn't using--then there should be no issue:  you're not using the property anyway.
