No. When a character is carried it is off the board for the duration of its movement and its powers/TA/feats/etc are unavailable. Only once it is set back down on the board at the end of the movement, you have access to it powers and such.

This is really easily accomplished with Running Shot and Charge: the attack occurs after the movement is over (and thus the carried character is set back on the map). However, HSS option 1 and transporter move and attack all have the attack occuring during the movement. If you're attacking, the movement isn't over (even if you have technically moved the maximum number of squares the character can move) and the carried character is not back on the map yet. The only way to benefit from a character's powers, TAs, and the like during HSS option 1 or transporter move and attack is to have the character already in position before begining the move and attack.

So in your case, if you want the PD TA to boost your AV, you must have the DEO Agent already in position in a square adjacent to where your transporter will make its attack.
