First, to be clear, I'm using the term "linker" in the same sense as the phrase "link time" in the name LTO, which means the linker is GCC. GCC is the program to which you feed .o files and get an executable out.

If instead of using GCC to link my .o files I use GNU 'ld', it will still work, right? And it looks like 'ld' doesn't know what LTO is.

Even GCC doesn't always know what LTO is. GCC 3 doesn't.

LTO could have been designed so that 'ld' and GCC 3 could not link the .o files created by gcc -flto, but it looks to me like it was a design objective that they be able to.
