Actually, yes it can. We have seen several cars with this type of issue in our shop that had current draws less than one amp that killed a battery in an hour or two.....


The drain in this case is high enough to possibly damage a multi meter set to milliamps.

Not necessarilly as most meters are fused to protect themselves if excessive current flow takes place, and nearly all digital meters "autorange" and will switch to a suitable range by themselves.
