Any place where string expansion takes place can use the ${run
expansion item to run a shell command.
Macros are simple textual replacement, so they are not relevant to
your question. That is, you can certainly define a macro whose value
contains ${run, but whether it will work depends on where the macro
is *used*. If the macro is used in a place where string expansion is
not done, ${run won't work. Either way, it doesn't matter that the
${run got there via a macro replacement.

The syntax would be
MY_IP = ${run {dig +short @MY_DNS MY_HOSTNAME} {$value}}
| local_interfaces = MY_IP : 127.0.0.1 : ::::1
But as best I can tell from the manual, local_interfaces is not
expanded, so this won't work as you wish.
