Sorry, but I prefer not to.
I use my own computer because it is optimised for behaving well during my presentations. It has the right PowerPoint version, the proper fonts, settings, etc…
Whenever I have had problems in the past, it was always where I have been persuaded to use somebody else’s computer, so I stopped using them. Think about it this way, doctors, painters, musicians and photographers all prefer using their own tools. It’s exactly the same with professional presenters.
Just too advise: I use an Apple Workbook Pro. I DO carry the conversion lead to plug into a VGA projector, IF the AV team do not have access to connect via Smart Link or HDMI.
