No, she can't. She's not even near the level that Accel is on, even when he's reduced to half of his original power.

Spoiler for light novel spoilers.:

Accel at half power could STILL beat up the second ranked Level 5, Teitoku Kakine, with relative ease even after said Level 5 awakened and powered up. The only people who can take down Accel are Touma and the most broken people of the magic side should he encounter them (which means saint level or above at least). Agnese is definitely not one of them. Her attacks wouldn't even get past his auto-reflect, much less damage him like Kakine at least managed to do once before he suffered total defeat. Do not underestimate a rule-breaking character.
