No, you do not - a LookML dashboard only needs to be included in a single model to be viewable.
Note, however, that the dashboard filters of a LookML do not have a way of denoting model. In other words, if Model A is the model including your LookML Dashboard, all dashboard filters of type: field_filter must reference fields that are in Model A.
- Change the filter type to not be field_filter (for example to type Date, Number, or String). Note that with this option, filter suggestions will not populate because filter suggestions require filter to be type: field.
- Get rid of all dashboard filters that reference the model you are not including the dashboard on.
