No. cryptsetup does not know or understadnm tokens. You can 
read the passprase from stdin (see man-page) and thereby construct
a wrapper involwing another software you have to supply that can
deal with a token. 

But you should know than an RSA token does not provide any secret 
when used to authenticate. It proves that it knows a secret, but 
that secret is not transferred. Hence an RSA token is not suitable
for use with disk encryption.
