Is it possible to select multiple coded values in a domain field?

No, it is not possible to select multiple coded values in a domain field in ArcMap. This is also a limitation in ArcGIS Online.
The Collector for ArcGIS app supports drop-downs through the use of domains, but currently only allows for a standard single-selection drop-down in the app. An idea has been suggested for this functionality in ArcGIS Ideas: Add multi-select to Collector for ArcGIS drop-downs.
However, this functionality is currently available in Survey123 for ArcGIS, where the multi-select is stored as comma delimited text in a resulting feature layer, as explained in the following help page: Multiple choice questions (select_multiple).
