Sure. This example in the manual uses .PHONY that way:
  http://www.gnu.org/software/make/manual/html_node/Special-Variables.html

I find it clearer to keep a target and its .PHONY dependency together:

.PHONY: x
x: prerequisites
        commands
...
.PHONY: y
y: ...

The manual says the prerequisites of .PHONY are combined:
