Could a solution be
simply to miss out the hardboard backing board and cut notches in the
side-walls of the base units to accommodate the pipes? Presumably the
backing board is there to give rigidity rather than load-bearing
strength so perhaps I could use some angle brackets instead in order
to give the base units rigidity?

Or put in a new backing board. Fix some timber strips to the bottom
& sides of the base unit & screw the hardboard on. Hides the pipes
but easily removed for access.

or screw 2 x 2 battens to the wall: that way you create a service gap for
low voltage & under unit lighting, extra sockets etc. either way is better
than hacking the units about.
