You can do it with SharePoint Management shell:
Set-SPSuiteBarBrandingElement -WebAppUrl http://sp2013.intranet.adventureworks.com -Text 'AdventureWorks Intranet'
Just replace the AdventureWorks Intranetwith the text you want.

Yes,You can edit by modifying the ms-core-brandingText class by seattle.master follow the steps given in below article to achieve the same.
You can do it with PowerShell to.
$webApp = get-spwebApplication "http://yourWebapplicationUrl"
$webApp.SuiteBarBrandingElementHtml = "<div class='ms-core-brandingText'>Insert new title here</div>"
$webApp.Update()
Or you could change the text and create a link out of it. I've done this so users can just click the title and get back to the root site.
$webApp = Get-SPWebApplication "http://yourWebapplicationUrl"
$webApp.SuiteBarBrandingElementHtml = "<div class=""ms-core-brandingText""><a href="http://LinkUrl">Insert new title here</a></div>"
$webApp.Update()
