It would be dependant upon what the Intended Purpose of the medical device was. Risk Management requirements affect how (many) parts of 60601 are applied.
But, a very quick and rough answer, would be - No (probably).
The exterior would (probably) have to be considered as a part that, whilst it is not an 'Applied Part' should be treated as if it was. That then demands very low leakage currents, in 'Normal' and 'Single fault Condition'.
You may be lucky and get away with the currents, but there are other requirements for APs, such as the maximum temperature allowed (can be as little as 43C - when measured with an ambient temperature of 40C - so, effectively, no temperature rise!).
Then, a tablet would have to be considered to be a 'hand held' device so the drop height (onto a hard surface) would be at least 1 metre. And the impact test - I don't think I'll try doing that to my iPad! (although the screen would not be tested).
