Yes, no problem, but you will probably need better antennas. what antennas are on both ends now?

you need better antennas, look at the calculator:
http://www.mikrotik.com/test_link.php,
it shows that your link is not possible until you increase antenna gain
something like this will make it possible:

or you could switch to R5H cards and then even a 14dbi antenna would be enough.
