There is no reason why it should not work, there is also a report and
benchmark of loop-AES on openwrt:

(100mb in 5m 32s means a speed of ca. 300kbyte/s, far away from a
regular PC)

You can look for the different fritz!box modding projects to get a
compiler and maybe the kernel sources. The last time I opened a
fritz!box, it had a 150MHz CPU, which would even further reduce the
possible throughput.

Some embedded routers (e.g. the Netgear WGT634U) also offer an embedded
crypto core based on the Sentry 5 (BCM55xx?) chipset - this probably
would highly improve loop-aes speed, but there is no driver available as
of yet.

Kind regards,
Georg Lukas
