Yes - you can see who has permission "Manage all programs" via the program administrator view in a specific program.
How to see this:
- Enter any program at your site
- Go to the programs settings tab and scroll down to section Program administrators
- Click on the small arrow next to the title Administrators for all programs and a you will get a list of every user in your site with permission "Manage all programs"
! TIPS !
Take a look at this list a couple of times a year and see if everybody in the list still should have admin permissions.
