Remove-ADComputer -Filter question

I need a script to remove computers from Active Directory based an input file with computer names. Here's the kicker, the last two characters of the computer name could either be a "-P" or a "-W", so my input files contains only the base computer name without the "-P" or "-W".  How do I pass computername-* to Remove-ADComputer?

From my research I gather a scriptblock might part of the answer, as per this: https://social.technet.microsoft.com/forums/windowsserver/en-US/8bcca597-e7ef-4eef-af5d-4cef1db4f7bc/error-variable-found-in-expression-is-not-defined. However, I have not been able to get it to work. Here's what I have so far:

$Count = 0
$Filter = [ScriptBlock]::Create({Name -like $($Computer.computer)+"-*"})
$Computers = Import-CSV "C:\Input.csv" 

ForEach ($Computer in $Computers) {
	
	#If computer is found, delete, else skip it.
		Try {
		Remove-ADComputer -Filter $Filter 
		
		Start-Sleep -Milliseconds 700
		$Count ++
		}
		Catch {
	       "Computer Not Found: $($Computer.computer)"
		}
	
	
	
	}
	"Count is: $Count"

Select allOpen in new window

The result is: Remove-ADComputer : A parameter cannot be found that matches parameter name 'Filter'.

Can someone help me get this working either with scriptblock or via another means? I would rather not modify the input file to contain the "-P" or "-W" suffix.

Thanks in Advance
