No, there is no JTAG. There is even no serial console when purchased,
you need to open the device and solder four-pin header or cable
directly to board to get it... See http://eko.one.pl/?p=openwrt-mr3420
(in Polish, last paragraph on page), or near the end of page at
http://wiki.openwrt.org/toh/tp-link/tl-mr3420 for some hint.
