Can I rename a variable in a SAS data set without input/output actions in data step, since I don't change the data stored in the set actually?
Yes, you could use proc sql instead:
proc sql; create table TEST as select
old_name as new name,
other_stuff,
more_other_stuff
from TEST;
quit;
Or proc datasets.

Doesn't this require the processing of every observation in the data step?
Or proc datasets.
I'm 100% sure this does not require processing of every observation in the data step. It doesn't even have to process one observation.
data have;
set sashelp.class;
run;
proc datasets library=work nolist nodetails;
modify have;
rename name=xxxxxx;
quit;
