When you are asking about "CheckBox" or "ComboBox", the question is: which one? Full type names, please.
As you did not specify what you are talking about, the answers you already received may or may not be applicable.

Not difficult to do.

When the user selects merchant, popupate the merchant dropdown and hide the other dropwdown.
When the user loads non-merchant. load the other dropdown.

Assuming the collections of names of merchants, and non-merchants, in the database that you wish the user to have access to during a session remain fixed, I'd seek to minimize loading the ComboBoxes from the database.

I suggest you consider creating two ComboBoxes, one for merchants, one for non-merchants: make them the same size, and set their locations to be the same, and load their contents from the database once.

Then, in the CheckBox.CheckedChanges Event Handler, something like this:

C#

private void cbxSelectNonMerchant_CheckedChanged(object sender, EventArgs e)
{
    if (cbxSelectNonMerchant.CheckState == CheckState.Checked)
    {
        cmbNonMerchant.Visible = true;
        cmbMerchant.Visible = false;
    }
    else
    {
        cmbMerchant.Visible = true;
        cmbNonMerchant.Visible = false;
    }
}

This assumes that you would start your application with the 'cbxSelectNonMerchant CheckBox.CheckState set to 'Unchecked, the 'cmbMerchant CombobBox visible, and 'cmbNonMerchant hidden.
