Can I install mini split units on the same wall?

I’m looking to install a 19 SEER Mitsubishi 24000 BTU mini split system on my garage. I’m limited in where I can put the outdoor unit, so my desired location happens to be directly behind where I want to put the indoor unit. The wall that will separate the units is 2-layer brick, so I expect that the lineset length will only be a max of 3-4 feet
I’ve seen plenty of warnings about putting the units too far apart, but never about too close together. Besides reducing the coolant pre-charge down from 25ft, are there any other concerns I should have about installing things very close together?
Thanks!

The usual reason I've seen for at least ten feet between inside and outside units is that you get some vibration and noise. I'd call Mitsubishi.
