Yes. Specifically, every Intel Mac still running Tiger*, as well as every Intel Mac that used the original Core Solo/Duo CPU, such as the first edition MacBook Pro. I also can't recommend targeting 64-bit Leopard unless you really know what you're doing, since the 64-bit frameworks in Leopard had some interesting bugs that weren't fixed until Snow Leopard came out... * Tiger's 64-bit support was limited to programs that only used the standard C and C++ libraries.
