The reason that a chord tone is the suspended 2nd (or 4th) is that it replaces the major or minor 3rd. So, you are correct here:
[QUOTE=dvenetian]But the sus2 is enabled when no 3rd is present in the chord, regardless of where it is positioned because it is a M2 note.
Would this be a correct statement?

Yep. The 9th is indeed the 2nd an octave higher. The relative position of a chord tone from the root note is very important, but is not the only factor in naming a chord.

For example, if I played this:

E|-----------------|
B|---3---5---------|
G|-----------------|
D|---5---5---------|
A|---3---3---------|
E|-----------------|

I would call it a Csus2 and a C major. I would not call it the 9th and the 10th, even though they are technically that interval distance from the root.

E|-----------------|
B|---6---5---------|
G|-----------------|
D|---5---5---------|
A|---3---3---------|
E|-----------------|

Same thing here, except Csus4 and C major. However, this:

E|-----------------|
B|---3---1---------|
G|-----------------|
D|---2---2---------|
A|---3---3---------|
E|-----------------|

This is better called a Cadd9 because the 3rd is present and the 2nd is an octave higher.

Hope this helps.
