Now that iTunes no longer syncs apps to iOS devices, can apps be removed from the folder that iTunes stored them in? (~/Music/iTunes/iTunes Music/Mobile Applications
in my case)
I have updated iTunes, and was surprised to see that the applications were not deleted.

Yes, the .ipa files can be safely removed/deleted, since iTunes 12.7 will no longer use them.
However, if an app is no longer available for download again, you can restore via the old .ipa file, per this TechCrunch article (includes Apple support links):
