If you think about it a file with nothing in it only has a newline in it...
Because the file as "spaces followed by a newline". So your answer is yes. But the file has to be empty for this to be the case.
That is probably why my 0 byte test failed.
here is my output using your test criteria.
-root:/tmp> echo "" > test # no blank in between
-root:/tmp> od -b test
0000000 012
0000001
-root:/tmp> echo > test #echo nothing
-root:/tmp> od -b test
0000000 012
0000001
-root:/tmp> echo " " > test # echo one blank character
-root:/tmp> od -b test
0000000 040 012
