Is Wayland tied specifically to Linux?

No in theory, mostly yes in practice so far. Although Wayland is intended to be portable among Unix-like systems, it's currently mostly limited to the Linux kernel because its reference implementation is being developed on GNU/Linux.

Wayland itself is a protocol. Its reference implementation Weston relies on a compositor that in native mode currently requires Kernel Mode Setting (KMS) and the evdev input event interface, which were originally specific to Linux although there are efforts to port them to other kernels. Although it's not intended that Weston be specific to Linux in the long run (e.g., there is a DragonFlyBSD port) almost all Wayland and Weston users are running on GNU/Linux right now.

Also, Weston can run in backward compatibility mode attached to an X server, and in this mode it runs on kernels other than Linux (e.g., there is a unsupported port to FreeBSD). I don't think this approach is much used outside of GNU/Linux either, though.
