Static electricity?  No.
Induced current.  Yes.

According to Wikipedia, an EMP can have both an electric field
and magnetic field.

If the EMP has a magnetic field component, then this could/would
induce a current in conductors.  I.e., a changing magnetic field
induces current, as per Faraday's law of induction.  The change
is from almost no change in the local magnetic field to a sudden
magnetic field from the EMP pulse.

If the magnetic field is sufficiently large, the induced current
could be large enough to burn up traces, resistors, inductors,
destroy ICs and damage static sensitive components.  It's very
possible that the induced currents are minimal even for a very
large EMP.  My recollection is that most of the field strength
laws are inversely proportional to either distance or the square
of distance.  I.e., the field strength declines rapidly the
further you're away from the source.  I don't know if that's the
case for an EMP pulse.  It may just be for things like magnets
and electromagnets which have static (non-changing) fields.
