You would have to calculate it yourself from:
Application.UsableHeight/Width
ThisWorkbook.Windows(1).Height/Width
Unprotect the WB, so you can change the Window properties.
Then move the window appropriately.

Is it possible to set the start up position of a workbook the same way as
a
UserForm - I'm looking to position a workbook (which has Protect Workbook
Window switched on) as CenterOwner (or equivalent).

Thanks
