I already know two ways to do that.
1. Testfor:
The testfor of 1.12 can be rewrited as, for 1.16:
execute at @e[tag=food] if @e[tag=head,distance=..0.5] run tellraw @a "Same Position Check"

2. Execute Store:
execute store result score @e[tag=head] X run data get entity @e[tag=head] Pos[0]; for X coordinate

execute store result score @e[tag=head] Y run data get entity @e[tag=head] Pos[1]; for Y coordinate

execute store result score @e[tag=head] Z run data get entity @e[tag=head] Pos[2]; for Z coordinate

execute store result score @e[tag=food] X run data get entity @e[tag=food] Pos[0]; for X coordinate

execute store result score @e[tag=food] Y run data get entity @e[tag=food] Pos[1]; for Y coordinate

execute store result score @e[tag=food] Z run data get entity @e[tag=food] Pos[2]; for Z coordinate

And then, test the scoreboards scores of the coordinates X,Y and Z:
execute if score @e[tag=head] X = @e[tag=food] X if score @e[tag=head] Y = @e[tag=food] Y if score @e[tag=head] Z = @e[tag=food] Z run tellraw @a "Same Position Check"
