In theory, yes, but you will need suitably large numbers of buffers and
so on, and the call could block for some time while waiting to send it
all.  If you can give details of the error that might help tell us what
your problem is.  lwIP should try to turn a big write like that into
many smaller writes (each less than 65535 bytes).
