With an expensive uncommon adapter you can. If a PCE EverDrive could support Arcade Card emulation it would be worth it for TG16&CD and US Turbo DUO owners. If you have a PC-Engine DUO I agree that it's not such a big deal to pickup the AC DUO card. But like The new Mega EverDrive supports the Sega CD Backup RAM cart function which similar to the arcade card, it would be handy if you could save significant money by having the device do both jobs. But again this speculates that the PCE ED even plans to use SDRAM and not Flash.
