You can’t expand macro from Lua but the following is possible:

\startluacode

values = {
	I  = "1",
	II = "2",
}

function test(arg)
	if string.find(arg,"\\macro") then
		arg = string.gsub(arg,"\\macro","")
		if values[arg] then
			context(values[arg])
		else
			context("Invalid index.")
		end
	else
		context("Invalid command.")
	end
end

\stopluacode

\starttext

\starttabulate
\NC \type{\macroI}   \EQ \ctxlua{test("\\macroI")}   \NC\NR
\NC \type{\macroII}  \EQ \ctxlua{test("\\macroII")}  \NC\NR
\NC \type{\macroIII} \EQ \ctxlua{test("\\macroIII")} \NC\NR
\NC \type{\foo}      \EQ \ctxlua{test("\\foo")}      \NC\NR
\stoptabulate

\stoptext
