Yes. See e.g. gcc/testsuite/gcc.dg/pr102892-{1,2}.c.
In one file you add
*> { dg-additional-sources "something-2.cob" }
and in the other either
*> { dg-do compile }
or even arrange for it to be skipped altogether.
When compiling the first test, it will just use dg-options from it
and add both the first and second test on the same command line.
The pr102892-1.c is in particular just dg-do link test (so it compiles and
links, but doesn't execute), so in testsuite/gcc/gcc.log then one can see
