Yes, I actually do that in my setups. E.g. I have a WIP (not posted
publicly yet, but planned) DTS for a certain RPi CM4 based device [1]. I
just have

#include "arm/broadcom/bcm2711-rpi-cm4-io.dts"

in there to start from the mainline CM4 IO-Board DTS. I should probably
switch to bcm2711-rpi-cm4.dtsi instead before sending a kernel patch,
but it works. :-)

Making that work is why $(LINUX_DIR)/scripts/dtc/include-prefixes/ is
added to the include paths for dtc in custom-dtbs.mk. What doesn't work
yet is using extra .dtsi files (as in ones you provide, not from kernel
source), but that should be easy to add.

Best regards,
Fiona
