Using the gravitational redshift should do it. If the earth is expanding
then the surface is in a weaker part of the earth's gravitational field
and clocks should go faster. Our best atomic resinators (say, for
example, a cessium atomic clock) would be accurate enough to detect
this. Since they haven't we can conclude the earth is not expanding at
all or not expanding enough to register using the gravitational red shift.

In addition any change of the distance between the surface of the earth
and the moon would be picked up by timing light reflections from the
lasers that the astronauts left on the moon. The only change detected is
accounted for by the fact the moon is moving away from earth because of
tidal slowdown of rotation. An expanding earth would not negate the
conservation of angular momentum.
