In the original Oberon report you can almost do this. One problem is in the
module headings. For Modula-2 we have:

DEFINITION MODULE foo;

for Oberon we have

DEFINITION foo;

so trying to pass off an Oberon module to a Modula-2 compiler doesn't work.
Otherwise, one would mostly be writing Oberon while avoiding use of the new
features of Oberon (e.g., type extension).

The intersection of Modula-2 and Oberon produces a language that is indeed
small, but perhaps not very useful.
