I'm looking for replacement for ADM2587E.

This is ADM2587E:

Can I just use cheap, not isolated RS485 transceiver like MAX485 connected to microcontroller TX, RX, DE/_RE via optocouplers and power it from isolated supply?

I realize, that it will take more space on PCB, but are there some other side-effects? Circuit is used for low speed communication (max baud rate is 38400).

Of course you can, as long as the digital isolators (e.g. optos) are fast enough for the baudrate you'll use.
