Maybe. This kind of test is hard to get right. It does look focused more to the front, especially if it really did grab that area as the focus point. However, how far away are you testing from? Your lens/camera combo may front-focus in this range and not so much at normal shooting distances. For that reason, and because the diagonal paper is hard to get aligned just right, I recommend one of the other ways to test focus as outlined in What is the best way to micro-adjust a camera body to a particular lens? — either the Moire Fringe Method, or (best and easiest, in my opinion), the Contrast-Detect-vs.-Phase-Detect Adjustment Method.
Note that front-focusing isn't a camera body thing, or strictly a lens thing either — it's the combination of the two, and especially with zoom lenses, a lot of compromise can be involved. It may front focus at 18mm and back-focus at 140mm — and if you make an adjustment for the former, the latter may get worse. And as noted above, it may be different at normal focusing difference than it is up close for a focus test.
