I like to use Array when I want a variable to be treated as a matrix.
[[Expression:||| Array[x,{2,2}] |||]]
This is probably not what you want since the output is a nested list. This is not the same as declaring a variable as a matrix. But now, this approach works:
[[Expression:||| a={{1,2},{3,4}}|||]]
[[Expression:||| Array[x,{2,2}] - a /. x[k__]:>a[[k]] |||]]
