No... u see in that photo how the stem is oriented? Its angled up right? Stems are reversible so realistically on this bike you could remove the stem topcap and loosen the two bolts on the stem along the steerer tube and flip it to make it a more aggressive position. (I realize thats not what you want but now you know what Im talking about)
Since the bike is more cruise than bruise (as I say) (more lax than race) the stem is probably already like it is in this picture and thus u have no option besides buying new stuffs.
Frankly, if the stem is that high up you're very near the limit of what most adjustable stems will allow in a positive angle, tho there are some extreme stems out there. You may want to consider swapping your bars out for risers like these:
They're available to a varying degree of riserness.
Yost knows his stuff though and he won't steer you wrong (no pun intended).
